otherwise, it is calculated as column 1. If both normalize and rescale are enabled, HP's implementation skips the rescale and does only the normalize. 5-8 OpenGL implementation guide Then: If normalization is disabled, then the square root in row i and column j ... Alternatively, an implementation may choose to normalize the normal instead of the matrix as row 1, and the left most column as dictated by the OpenGL Spec. programming hints If rescaling is disabled, f is 1, otherwise f is computed as follows: Let mij denote the matrix element in the previous fully transformed normal equation...
